Esc sigma-4s panel: common questions

What microcontroller does the Esc sigma-4s panel use?

The Esc sigma-4s panel is built around the STM32F411RETx, from the STM32 family.

How big is the Esc sigma-4s panel PCB?

The Esc sigma-4s panel measures 77 × 127 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Esc sigma-4s panel?

121 components, from 29 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Esc sigma-4s panel design files?

From the mstoilov/sigmadrone-esc repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Esc sigma-4s panel design in my own project?

The repository has no license, so all rights stay with mstoilov. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Esc sigma-4s panel without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
